| iPhone charger teardown: quality in a tiny expensive package "Disassembling Apple's diminutive inch-cube iPhone charger reveals a technologically advanced flyback switching power supply that goes beyond the typical charger. It simply takes AC input (anything between 100 and 240 volts) and produce 5 watts of smooth 5 volt power, but the circuit to do this is surprisingly complex and innovative." Quite fascinating, although I'm not sure just how much the mentioned advantages really matter beyond bragging rights. http://osnews.com/story/25978/iPhone...siv e_package |
